Advice for a pure

Looking for advice on making a zerker pure, im guessing 50 defense because of the new update. looking for what quests i should do or a guide even i havent played in a while. and how much def xp will i get from doing all the quests needed. any advice is helpful!

 

Your best hope is looking at a youtube video or finding a thread about zerkers, but it will be out-dated so you will have to change items around so that it works
